Greptile Summary

This release (v0.13.0) introduces two major structural changes: a slim/heavy package split (agentex-client for the pure REST client, agentex-sdk for the full ADK overlay) and a config module promotion that moves canonical deployment/agent config models from agentex.lib.sdk.config.* / agentex.lib.types.* into the new agentex.config.* namespace, with back-compat re-export shims keeping old import paths working.

• Package split: pyproject.toml becomes agentex-client (6 slim deps); the new adk/pyproject.toml becomes agentex-sdk with all ADK/CLI/LLM deps, pinning agentex-client>=0.12.0. A scripts/check-slim-deps CI guard prevents dep drift.
• Config promotion: All model classes are now in agentex.config.*; shims in the old paths re-export the identical class objects so isinstance checks remain correct across import styles. AgentEnvironmentsConfig.from_yaml() is replaced by the standalone load_environments_config() helper (kept in the shim module to preserve slim-safety).
• Tracing optimisations: span-start writes are skipped by default (end-only ingest via AGENTEX_TRACING_SKIP_SPAN_START), and the span-queue batch size / linger window are both increased for higher throughput. A tutorial deadlock caused by using LangGraph's ToolNode (a Runnable) inside a Temporal-wrapped workflow node is also fixed.

Confidence Score: 5/5

Safe to merge — all changes are well-tested, breaking changes are documented in the CHANGELOG, and the back-compat shims are covered by identity-checking tests.

The package split and config promotion are structural refactors with comprehensive shim tests confirming symbol parity and class identity. Tracing optimisations default to the new behaviour but are runtime-toggleab...

Greptile Summary

This is the automated 0.12.0 release PR, primarily migrating the entire dev toolchain from rye to uv 0.10.2 and bumping the version consistently across pyproject.toml, _version.py, and the release manifest.

• All CI jobs (lint, build, test), the publish workflow, the devcontainer, and helper scripts (bootstrap, test, lint, format, publish-pypi) are updated to use uv commands; the uv version is uniformly pinned to 0.10.2.
• The devcontainer base Python image is upgraded from 3.9 → 3.12, aligning with the new test matrix minimum.
• Lock files (uv.lock, requirements-dev.lock, requirements.lock) are regenerated to reflect the new toolchain.

Confidence Score: 5/5

Safe to merge — this is a clean tooling migration with the uv version pinned consistently at 0.10.2 across CI, the publish workflow, and the devcontainer.

The rye-to-uv migration is internally consistent: all three CI jobs, the publish workflow, and the devcontainer use the same uv 0.10.2 binary. The version bump is coherent across all version-bearing files. The two observations (broad required-version floor and the 3.11 test-coverage gap) are non-blocking quality notes that don't affect runtime correctness of the published package.

No files require special attention; scripts/test and pyproject.toml have a minor declared-vs-tested Python version gap worth cleaning up at leisure.

Important Files Changed

Filename	Overview
.github/workflows/ci.yml	Migrated all three jobs (lint, build, test) from rye to uv 0.10.2 via astral-sh/setup-uv; version is consistent across all jobs.
.github/workflows/publish-pypi.yml	Updated from rye to uv 0.10.2, now consistent with CI; previous version mismatch (0.9.13 vs 0.10.2) has been resolved.
pyproject.toml	Bumped to 0.12.0, migrated build tooling config to uv; requires-python declares 3.11+ but test matrix only covers 3.12-3.13.
scripts/test	Migrated from rye to uv; test matrix now runs 3.12 and 3.13 only, leaving Python 3.11 (declared supported) untested.
scripts/bootstrap	Replaced rye sync with uv python install + uv sync + uv export for lock file generation.
.devcontainer/Dockerfile	Upgraded base Python from 3.9 to 3.12 and replaced rye install with uv 0.10.2 copied from the official image.
src/agentex/_version.py	Version bumped to 0.12.0, consistent with pyproject.toml and .release-please-manifest.json.
bin/publish-pypi	Replaced rye build/publish commands with uv build + uv publish.
